THOMAS T. STRODE, OF COATESVILLE,PENNSYLVANIA.

GRAIN WINNOWER AND WEIG-HER.

Specification of Letters Patent No.

To all whom it/may concern: j

Be it known that I, THOMAS T. STRODE, of Coatesville, in the county of Chester and State of Pennsylvania, have inventeda new W innowing and \Veighing Grain; and I do hereby declare the following to be a full and clear description thereof, reference being had to the annexed drawings, making part of this specification.

Figure 1 represents an elevation of the machine, the receiver being in a position to receive the grain from the winnowing ma chine. Fig. 2 is a vertical longitudinal section of the machine, the receiver having been filled with grain and ready to be re moved. Fig. 3 is a perspective view of the balance lever weigher. Fig. i is an end view of the shoe with its riddles.

The same letters of reference indicate the same parts on the above figures.

The nature of my invention and improvement consists in so combining a balance lever weigher withthe lower portion of the frame of the winnowing machine, that the grain may be received from the latter into a portable receiver, mounted upon the rear ends of said balance lever weigher, while the. frontward projecting ends of the latter are graduated and furnished with adjustive pounds or bushels whereby the grain when cleaned is discharged into a receiver, weighed and conveyed into any convenient pla'ceanddischarged or bagged by attaching the'receiver to any suitable hoisting apparatus for elevating itto any suitable height to allow the bag to be attached tothe bottom thereof.

My improvement also consists in arranging beneath the ordinary riddles, a long oscillating shoe provided with a screen,- whereby the grain is received from the upper shoe, screened and deposited into the portable receiver of the. balance lever weigher.

A, is the frame, B, is the hopper, C, is the fan shaft, D, are the fans, E, is the fan case, F, is the crank handle, and G, H, the gearing whereby the fans are rotated.

I, is a rod conecting the pinion G of the fan shaft C. to a crank X, whereby the lower shoe is operated.

J, is the upper shoe suspended by two crank arms (a) at the rear to the frame A and by two downward projecting crank 8,763, dated February 24, 1852.

arms 5 of a rock shaft 0 having its bearings 11] the frame; from one end of this rock shaft pro ects an upward arm cl from which a rod 6 extends to and is attached eccenrearward during the vibrationof the shoe,

and at the same time allow them to be raised or lowered as seen. in Fig; The front ends of the riddles are supported by means of pins projecting therefrom into grooves formed in the sides of the shoe whereby the front ends of the shoe may also be adjusted Two rods t t are secured vertically in eyes to the sides of the shoe, which serve to prevent the pins of the riddles from. moving out of the grooves and thus the riddles are confined and adjusted as required. I

Beneaththe-upper shoe J, there is placed another shoe K extending from the front of the frame to directly above the portable grain receiver of the weigher and provided with an inclined board j to direct the screenings from the shoe into a box below, and also provided near its cent-er with a screen 7: to receive the grain from the upper shoe and separate the cheat and cockle from the grain and allow the former to pass into a box Z and the latter into the portable re ceiver mounted upon the rearward ends of the balance weigher. This shoe is suspended by two crank arms m at the rear thereof and also by two arms (11.) projecting from a rock shaft 0 having its bearings in the sides of the frame. Beneath the long shoe K is arranged abalance lever weigher L suspended upon two pivots or knife edged bearings 79, 70, projecting from either side thereof into the side timbers of the frame A.

The rearward ends of the balance lever frame areelevated and extend to the front of the frame and are connected by a bar and graduated with holes or notches indicating bushels, peeks and p'ounds and furnished with weights M, whereby the balance lever frame may be adjusted to weigh any required quantity.

The front end of the balance lever frame is supported by a transverse timber r Fig. 2 of the frame A.

The balance lever frame is braced and connected by a horizontal transverse bar T.

The rearward ends of the balance lever frame extend beyond the frame A and from ways L, tapering nearly to a point upon which is placed the receiver 0, resting upon four flanged. rollers P, whereby the said receiver O is rendered portable and moved on to the ways of the balance lever frame and removed therefrom after the grain shall have been weighed.

The ways upon which the receiver is mounted are furnished with stops Q Q to arrest the receiver when being adjusted thereon.-

The inner pair of flanged wheels P are 7 arranged near the center of the receiver so as to be near the fulcrum of the weighing beams, while the other pair of wheels are mounted at the rear end of the receiver,

whereby the latter is made to balance the weighing beams when empty and properly adjusted thereon. The portable receiver 0 is provided with a slide door or gate R in the bottom thereof which is turned horizontally to open and close an aperture or opening in the bottom of the receiver through which the grain when weighed is discharged. i

The openings S of the fan case are made i l somewhat after the form of an egg, whereby a large supply of air is obtained at the point where the paddles actfreely thereon and send it throughthe riddles and whereby the fans are relieved from the back pressure of compressed air which usually accumulates in the rear part of the fan case when the openings are circular.

The operation of the weigher is as follows: The portable receiver having been run on to the ways L as far as the stops Q, Q

and retained in its proper position by the flanges of said rollers fitting against the insides of the ways, and the weights adjusted on the graduated arms of the weigher to weigh the desired number of bushels as may be indicated by scales or otherwise so that the frontward ends of the graduated arms of the lever frame will rest upon the transverse beam 1" of the frame, and the receiver w1th its ways elevated as shown in Fig. 1.. The grainas it is cleaned from its impurities, passes from the upperishoe J on to the lower oscillating shoe K, and from thence delivered by its oscillating motion over the end of said shoe into the grain receiver, while the cheat and cockle falls through the screen k into a box Z. When the required number of bushels of wheat shall have been delivered into the receiver, the

ends of the weighing beams upon which the receiver rests will be caused to preponderate and form inclined planes and allow the receiver to pass from the ways and the balance frame again to assume its proper position and an empty receiver placed upon the ways in the manner above described. In this manner the grain is cleaned by the winnowing machine, weighed by the balance lever weigher and conveyed and discharged in any convenient place by opening the slide door or gate R of the latter. The receiver may be made in any convenient form and size to receive the desired number of bushels of grain. This winnowing machine is not increased in height by the addition of the balance lever weigher, as the horizontal position of the lower shoe gives ample room for the arrangement of said weigher beneath the same. A shallow box may be placed beneath the end of the shoe K at the bottom of the frame for the purpose of catching the grain that falls from the shoe during the interval of'removing the filled receiver and replacing an empty one. I however contemplate arranging a valve or hinged door desire to secure by Letters Patent, is:

1. Combining a balance lever weigher with the lower portion of the winnowing machine whereby the grain when cleaned is weighed and removed therefrom bva portable receiver as described and represented.

2. I also claim constructing the balance lever weigher as represented and mounting the same upon pivots or knife edge bearings 19 whereby its rearward projecting ends L are made to serve as ways or inclined planes upon which is mounted a portable receiver 0 so as to balance the weigher, while its frontward ends are graduated and furnished with weights M bv which the number of bushels weighed at each time may be indicated as described.

In testimony whereof I have hereunto signed my name before two subscribing wit nesses.

THOMAS T. STRODE.
